Abstract

The invention relates to ecology and environment protection, more specifically to ecology of the nuclear industry and is embodied in the form of a method for removing radionuclides, preferably of II-VII groups from radioactive aqueous solutions. The inventive method consists in at least singly bringing a solution into contact with a complexing sorbent containing an active sorbing layer which is immobilised on a solid carrier embodied in the form of a cellulose or a synthetic polymer and comprises ethylenediamine, or diethylenetriamine or triethylenetetramine or tetraethylenepentamine or polyethylenepolyamine or polyethylenepolyamine with copolymers condensed with complexons selected form a group containing carboxyl-containing complexons with fragments NHCH2COOH,-N(CH2COOH)2, compexons with phosphonic groups arrangement N(CH2PO3H2)2, hydroxyl-containing complexons with fragments = NCH2CH2OH, HOCH2CH2-N- CH2COOH, HOCH2CH2-N-CH2PO(OH)2. The inventive method makes it possible to remove radionuclides contained in an ion and a colloid state from solutions containing high concentration of additional impurities, the used sorbent preserving the sorption properties thereof after repeated regenerations and being capable to remove radionuclides in a dynamic and static modes at different pH of the treated solution.
